Hello,
Sorry there is no direct option in theme settings available for that. But you can add a back button in the mobile header.
Navigate to WoodMart > Header Builder > Edit Current Header > Switch to Mobile Header > Add the Text/ HTML elements and paste the following code:

<button id="hdr_bck_btn" onClick="window.history.back()"><i class="fas fa-chevron-left"></i></button>
Then, Please try using the below Custom CSS code and paste it to Dashboard >> Theme Settings >> Custom CSS >> Custom CSS for mobile section:
#hdr_bck_btn {
color: #7f2f2f !important;
background-color: #396539;
}
Best Regards.
